1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
receive an uplink grant scheduling an uplink transmission associated with a repetition quantity, the uplink grant including a bit indicator set including a number of bit indicators that has a same quantity as the repetition quantity;
multiplex each repetition of the uplink transmission by a bit quantity of Hybrid Automatic Repeat Request (HARQ) acknowledgement (HARQ-ACK) feedback bits associated with a respective bit indicator of the bit indicator set; and
transmit a first repetition of the uplink transmission, the first repetition multiplexing a quantity of HARQ-ACK feedback bits of HARQ-ACK feedback for a physical downlink shared channel (PDSCH) scheduled by a downlink grant, the first repetition and the HARQ-ACK feedback overlapping in a time domain, wherein the quantity of the HARQ-ACK feedback bits are based on a first bit indicator of the bit indicator set.
